[SOLVED] 2 C++ related questions

[Ninjakreborn]

1) I have been studying/playing with C++ for awhile.  However I have always been curious how to go above and beyond command line applications (which is all I can write currently) and start developing windows applications (and eventually making them compatible with MAC, Unix, and Linux).  Basically this is the general code below i have seen in a variety of places.

However this code throws a variety of errors..is there a way to make this code work.

int WINAPI WinMain(HINSTANCE hInstance,
	   HINSTANCE hPrevInstance,
  		   LPSTR lpCmdLine,
  		   int nCmdShow);

2) What is the difference between a "Struct" and a "Function" in C++. I have seen a few examples where Struct is used instead of Function?

1:

Are you including Windows.h?

 

 

2:

In C++, a struct is a class, but all members default to public rather than private (and inheritance for that matter). It is totally different from a function.

Ah ok thank you for both answers.

If by "Windows Applications," you mean applications that are coded using the Windows API for graphical stuff, then good luck making those compatible with Mac/linux.  The Windows API is just on Windows ;p.  But nevertheless, I wish I were good with the WinAPI .
